I know the characters are lacking from a modern perspective but I can't reach much higher quality at the moment. :) Morrowind is the visual level I try to reach with them but thats really it, however, I don't see what you mean with the textures.
Are you sure its the textures themselves you find lacking and not the shaders and lighting upon them? Also keep in mind that I don't aim to reach current standarts of graphics. Still. Thanks for the feedback.

Thank you! I'll upload a list of mods that alter the appearance of Oblivion in a very aesthetic way soon. that way you can play a great game with even better visuals. The modding community really made it an absolute masterpiece.
